Recommanded Product: 3229-00-3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Pentaerythrityltetrabromide, is researched, Molecular C5H8Br4, CAS is 3229-00-3, about Synthesis of star polymethyl acrylate by SET-LRP at ambient temperature. Author is Ding, Wei; Lv, Chongfu; Sun, Ying; Luan, Huoxin; Yu, Tao; Qu, Guangmiao.
The star-shaped polymethyl acrylate (PMA) was synthesized by single electron transfer living radical polymerization (SET-LRP) at 30° in DMSO, using 2,2-dibromomethyl-1,3-dibromopropane as the multi-functional initiator, Cu0 powder and tris-(2-dimethylamino ethyl)amine (Me6-TREN) as catalyst. The structure of polymer was analyzed by 1H NMR, and the results showed that the star-shaped PMA had perfect chain ends (-Br) retention. In addition, the polymerization proceeded smoothly and the time dependence of ln([M]0/[M]) was linear, which could indicate a first order propagation rate with respect to both radicals and monomer concentration, the polymerization was the living polymerization The Mn and Mw/Mn of polymer were being measured by Gel Permeation Chromatog. The kpapp = 0.0367 h-1 and the conversion was 36.3% at 16 h, meanwhile the MnGPC of the polymer was 13,300 and the Mw/Mn was 1.40.
